I have worked alongside someone for a year. We get on well, but I think she views our relationship as a 'friendship', whereas I see it as more of colleagues- we have never socialised outside work.
She has invited me (+1) to her wedding, but no-one else in the office! I was genuinely surprised to be invited, as we don't really know each other that well!
Should I accept graciously and buy a new frock? My BF thinks it is a bit odd as we won't know anyone there. I have never met her fiance and my BF has never met her!
